摘要:
A printing device comprises a printing unit which prints an image on a sheet according to a print command, a judgment unit which judges whether a total adhesion amount of a print agent adhering to the sheet for the image printing exceeds a prescribed threshold value or not based on inputted print data, and a control unit which executes a process for reducing the total adhesion amount of the print agent when the total adhesion amount is judged to exceed the threshold value by the judgment unit.

Method of printing images on halves of both sides of sheets by passing each sheet seriatim four times directly in succession through a printing station (4), thereby printing the four halves of the sheet. The sheets thus printed and together folded double form a book in which the sequence of the images corresponds to the sequence of the original images. A device for performing this method comprises a sheet turn-over path (8) along which a sheet passed through the printing station (4) can be returned to the printing station and a sheet discharge path (7) along which a sheet passed through the printing station (4) can be fed to a collector tray (12). Control means control that a sheet after the first three passes is fed into the turn-over path (8) and after the fourth pass into the discharge path (7) and a time element so controls the time of passage of a sheet through the printing station (4) that on the first and fourth pass of a sheet an image is printed on a half of the sheet which, as considered in the direction of passage, is other than the half printed in the second and third pass of the sheet. For making a book from a set of originals printed on one side the device is provided with a document feeder (21,22) for feeding originals from both sides of a stacked set of originals (20) and a deposit device (29) having two deposit plates (30,31), in which, for printing a sheet, first two originals are fed from one side of the stack (20) and deposited on one of the deposit plates (30,31) and then two originals are fed from the other side of the stack (20) and deposited in reverse orientation on the other deposit plate. For keeping the last page(s) of a book blank when the number of originals is less than a multiple of four, the document feeding operation can be inhibited at appropriate times in a print cycle being otherwise the same.

A method for controlling an image forming apparatus (100) configured to form an image by transferring an image generated based on input image data onto an intermediate transfer member (405) page by page and further transferring the image transferred onto the intermediate transfer member (405) onto a sheet includes transferring, after transferring an image of a first page onto the intermediate transfer member (405) based on the input image data, an image of a second page, which follows the first page, onto the intermediate transfer member (405) side by side with the image of the first page, which has been transferred onto the intermediate transfer member (405), determining whether the image of the second page can be transferred side by side with the image of the first page during a time period in which the intermediate transfer member (405) having the transferred image of the first page is rotated to a transfer position for the image of the second page, controlling, if a result of the determination is negative and predetermined information has been received, the image of the second page to be transferred side by side with the image of the first page after rotating the intermediate transfer member (405) at least one revolution after transferring the image of the first page onto the intermediate transfer member (405); and controlling, if the result of the determination is negative and the predetermined information has not been received, the transferred image of the first page to be transferred onto the sheet, without transferring the image of the second page side by side with the transferred image of the first page, after transferring the image of the first page onto the intermediate transfer member (405).

An image recording device comprises: a first and second recording heads (11, 12) formed of recording elements cyclically arrayed, which are continuously arrayed with an overlapped region; image data distributing means (2) for distributing image data to these recording heads (11, 12); image data distribution region variation means (3) for setting an image data distribution region where the image data of each pixel is distributed to both the recording heads (11, 12) by the image data distributing means 2; correction parameter storage means (5) for storing a correction parameter for correcting the difference in the image density properties between the image data distribution region and the other region due to phase difference between the recording heads (11, 12); and image data correcting means (4) for correcting the image data in the image data distribution region based upon the correction parameter.

An image forming apparatus (1) comprising, an original reading means for reading an image of an original, an image forming means for forming the image read by the original reading means on a sheet, a sheet conveying means (17,18) for conveying the sheet to the image forming means, a re-supplying means (27) for directing the sheet on which the first image was formed by the image forming means to the image forming means again by re-circulation of the sheet to form a second image on the sheet, and a timing control means for changing the timing for the formation of the first image and the timing for the formation of the second image to form the first and second images on the single sheet side by side.
